Description:

This diagnostic trouble code is generated when the control unit registers a supply voltage of less than 9 volts. Low supply voltage can affect the performance and reliability of the control unit.

Reaction:

The control unit may operate erratically or fail to perform certain functions due to insufficient power supply. This can lead to various operational issues.

Recommendations:

• Inspect Power Supply:
  • Check the power supply connections to the control unit for any loose or corroded connectors. Repair or replace as needed.
• Test Battery and Alternator:
  • Ensure that the battery and alternator are functioning correctly and providing adequate voltage. Replace if necessary.
• Check Wiring:
  • Inspect the wiring between the power source and the control unit for any signs of damage or wear. Repair or replace damaged sections.
• Secure Connections:
  • Ensure all power supply connections are secure and free from contamination.

Note:

Maintaining a stable and adequate power supply is crucial for the reliable operation of the control unit. Regular checks can help prevent low voltage issues.
